What are the key features of SFM-129-L2-L-D-A-P-TR?
- 58-position dual-row SMT socket at 0.050" pitch enabling high-density mezzanine and board-to-board interconnects
- High-reliability construction with gold-plated contacts rated for 500+ mating cycles in demanding industrial and instrumentation applications
- Tape-and-reel (TR) packaging ensures consistent orientation for automated pick-and-place SMT production lines
What is SFM-129-L2-L-D-A-P-TR used for?
The SFM-129-L2-L-D-A-P-TR is designed for compact mezzanine board stacking, daughter-card interfaces, and high-density module interconnects in industrial automation, test and measurement, and communications equipment. Its 58-position dual-row layout at 0.050" pitch provides twice the density of standard 0.100" pitch solutions in the same connector length, making it valuable for space-constrained multi-layer PCB assemblies. The tape-and-reel format integrates seamlessly into high-volume SMT production workflows.

Frequently Asked Questions
What pin density advantage does the SFM-129-L2-L-D-A-P-TR offer compared to a standard 0.100" pitch dual-row socket strip with a similar footprint?
The SFM-129-L2-L-D-A-P-TR operates at 0.050" pitch across 58 positions in a dual-row configuration, providing approximately twice the contact density of a 0.100" pitch equivalent occupying the same PCB length. For example, a 0.100" pitch dual-row strip of the same body length would accommodate roughly 29 positions, whereas the SFM-129-L2-L-D-A-P-TR carries 58 positions, making it ideal for FPGAs, SoCs, and signal-dense module interfaces.
In which compact embedded system architectures is the SFM-129-L2-L-D-A-P-TR most commonly specified?
The SFM-129-L2-L-D-A-P-TR is frequently specified in mezzanine-style compute modules, FPGA daughter cards, and industrial I/O expansion boards where 58 signals must be routed between PCBs in a stack height of less than 5 mm. The 0.050" pitch dual-row socket reduces the connector footprint by 50% versus 0.100" pitch alternatives, allowing designers to reclaim board area for power circuitry, decoupling capacitors, or additional signal layers in 4-layer to 8-layer PCB stackups.
How does the tape-and-reel packaging of the SFM-129-L2-L-D-A-P-TR affect procurement and production planning for high-volume builds?
The tape-and-reel (TR) format of the SFM-129-L2-L-D-A-P-TR is compatible with standard SMT pick-and-place machines using EIA-481 reel specifications, which eliminates the need for manual component loading and reduces placement cycle time per board. For production runs exceeding 1,000 units, this translates to measurable throughput improvements over tray-packaged alternatives. Buyers should confirm reel quantity and component orientation with SAMTEC at time of order to align with automated line setup requirements for this 58-position, 0.050" pitch part.
